Tenchi Muyo! Toko Muyo

Tenchi Masaki was leading an ordinary life at seventeen until he stumbled into a cave and accidentally freed Ryoko—a space pirate who had been sealed inside for seven hundred years, mistaken by the locals for a demon. One alien visitor would have been enough. Four more arrived in the wake of that first release, each drawn to the Masaki household for their own reasons and each harboring some form of romantic interest in Tenchi. While navigating that chaos, Tenchi begins learning things about his own heritage that no one had ever thought to mention.
